Pala (Myristica fragransa) mengandung senyawa metabolit sekunder yang menunjukkan aktivitas farmakologi. Namun, bagian perikarpium terutama bagian nonvolatil belum banyak dilaporkan. Tujuan dari penelitian ini sebagai screening awal dengan melihat potensi dari senyawa yang dihasilkan perikarpium pala.Dua belas senyawa digambar dua dimensi, dianalisis menggunakan software dan server prediktor. Software yang digunakan adalah Marvin Sketch, ChembioDraw kemudian dianalisis sifat fisikokimia senyawa tersebut. Selanjutnya, server predictor untuk melihat karakteristik farmakokinetika dan toksisitasnya. Berdasarkan analisis sifat fisikokimia senyawa terbaik yaitu licarin (titik didih, titik kritis temperature dan refraksi molar), guaiacin (titik leleh), dan virolane (titik kritis tekanan). Hasil analisis Lipinski menunjukkan senyawa stigmasterol dan b-sitosterol tidak memenuhi kriteria Lipinski.. Selain itu data farmakokinetika menunjukkan stigmasterol, b-sitosterol, asetoneoglinan memiliki kelarutan dalam air yang rendah. Nilai permeabilitas CaCO-2 dan intestinal absorption semuanya memenuhi. Licarin termasuk substrat P-glikoprotein. Volume Distribusi menunjukkan semua senyawa terikat protein serum. b-sitosterol permeabilitas terhadap sawar darah-otak yang paling baik dan erythro-(7S,8R)-∆8’-7-acetoxy-3,4,3’,5’-tetramethoxy-8-O-4’-neolignan permeabilitasnya buruk. Surinamensin menunjukkan permeabilitas terhadap sistem saraf pusat yang tidak dapat berpenerasi. Elemicin dan surinamensin tidak dimetabolisme oleh enzim sitokrom CYP3A4. B-sitosterol memiliki klirens paling tinggi. Semua senyawa menunjukkan tingkat toksisitas yang rendah untuk penggunaan kulit (kecuali elemicin) dan tidak toksik bagi hati.ABSTRACT Nutmeg (Myristica fragransa) contains secondary metabolites that exhibit pharmacological activity. However, the pericarpium, especially the nonvolatile part, has not been widely reported. The purpose of this study was as an initial screening by looking at the potential compounds produced by the nutmeg pericarp. Twelve compounds were drawn in two dimensions, analyzed using software and predictor servers. The software used is Marvin Sketch, ChembioDraw and then the physicochemical properties of these compounds are analyzed. Furthermore, the predictor server to see the pharmacokinetic characteristics and toxicity. Based on the analysis of the physicochemical properties of the best compounds, compound licarin (boiling point, critical point of temperature and molar refractivity), guaiacin (melting point), and virolane (critical point of pressure). The results of Lipinski's analysis showed that stigmasterol and b-sitosterol compounds did not meet Lipinski's rule. In addition, pharmacokinetic data showed that stigmasterol, b-sitosterol, acetoneoglinan had low solubility in the water. The values of CaCO-2 permeability and intestinal absorption were all satisfactory. Licarin is a P-glycoprotein substrate. The Volume Distribution shows all the compositions of the serum proteins. B-sitosterol with the best permeability to the blood-brain barrier and erythro-(7S,8R)-∆8'-7-acetoxy-3,4,3',5'-tetramethoxy-8-O-4'-neolignan bad permeability. Surinamensin exhibits permeability to the non-permeable central nervous system. Elemicin and surinamensin are not metabolized by the cytochrome enzyme CYP3A4. B-sitosterol has the highest clearance. All compounds show a low level of toxicity for skin use (except elemicin) and are not toxic to the liver.

Several studies have shown that pure compounds from west sumatera medicinal plants have beneficial therapeutic effects so that they are potential candidates for active pharmaceutical ingredients (API). Andalas Sitawa Fitolab has been able to produce 10 pure isolates. The development of a new drug candidate requires an in silico study to predict physicochemical properties, potential target, and toxic properties. The purpose of this study was to initially screen the structure of candidates to predict the potential the compound as an API by using big data and machine learning. The chemical structure were analyzed using software and servers. The Software used was Marvin Sketch, QSAR Toolbox, Swiss Potential Target and ChemBioDraw. Results showed that log P of compounds revealed in a range of -0.54 to 4.64, Polar Surface Area (PSA) in range of 20.23 to 315.21. Asiaticoside did not meet Lipinski's rules. Compounds with high potential hazard were catechin, curcumin, andrographolide, asiaticoside deoxyelephantopin, ethylmethoxycinnamate, alpha-mangostin and piperine. The compounds such as curcumin, alpha mangostin, plumbagin, and piperine were predicted to have spesific target proteins. This study concluded that asiaticoside compounds have a high potential hazard, if it was developed as an API.Keywords: analysis of physical-chemical properties, in silico, pure isolate, toxicology

Sumatran lichen has the potential as antiviral, pure isolates that have been isolated and developed as prospective compounds for COVID-19 treatment. Computational methods were used to accelerate the discovery and screening of potential new compounds. The molecular structures of the isolated compounds such as Lobarin, Atranorin, Methyl 2,4-dihydroxy-3,6-dimethylbenzoate, Methyl 3-formyl-2,4-dihydroxy-6-methylbenzoate, Ethyl 3-formyl-2,4-dihydroxy-6-methylbenzoate, and Lobaric acid were drawn, then their activities were analyzed, processed by docking with ACE2 protein, and tested for Druglikeness. The activities and druglikeness were determined in the Swiss ADME program, while the ACE2 docking was processed by Blind Docking in Arguslab, AutoDock Vina, Open Babel, and Discovery Studio Visualizer programs. All compounds bound to the ACE2 protein, as apparent from the number of hydrogen bonds between the two. The Gibbs free energy was in the range of -5.6 to -7.0, and the best one was obtained from atranorin. As for lobarin, this compound was found to be non-drug-like.

Eco Enzymes can accelerate biochemical reactions to produce enzymes that break down fruit or vegetable waste. It was from this waste is one way of waste management that utilizes kitchen scraps to produce beneficial liquids. Community service was conducted in the Limau Manis Village of Padang City. Pre-tests and post-tests in the form of questions were conducted to assess the community's understanding of the Eco Enzyme material provided. Educational materials about the theory and importance of the Eco Enzyme product were provided by a lecturer in Pharmaceutical Chemistry from the Faculty of Pharmacy at Universitas Andalas regarding its uses and the products that can be sold. The theory material was made into a booklet and given to participants to take home and read again. Direct practice was conducted on making Eco Enzyme from orange peel waste obtained from fruit sellers. The T-Test results obtained a t-value of -5.047 with a p-value of 0.0001 (smaller than the alpha of 0.05). This value shows that this community service activity significantly improves the community's understanding of Eco Enzyme. In the future, an Eco Enzyme product in the form of a liquid that can be used will be obtained.

Ginger (Zingiber officinale), a member of the Zingiberaceae family, has been shown to have anti-inflammatory, antioxidant, anti-nausea/antiemetic, antibacterial, cytotoxic, and antidiabetic effects. Red ginger rhizome has been used as a spice, culinary flavoring, and herbal medicine. Our research shows that gingerol has the potential to be an anti-oxidant. The Assay of Antioxidant Activity using FRAP method is used to screen potential activity. The gingerol concentration of Ginger-Ethanolic extract (MGE) was 2.8 %, and the antioxidant activity was 1.96 mmol Fe(II)/100g, to the antioxidant activity of gallic acid that is 9.34 mmol Fe (II)/100 g. The equation for the standard calibration curve for comparison (6)-gingerol obtained is Y = 23.124 X + 1509.65. It can be concluded that MGE has antioxidant potential activity.
